Alignment of the M1-P-M2 region of KirBac family with three non-Kir (Shaker Kv, a sequence from Dienococcus radiodurans that belongs to the Kbac6TM1 family and KcsA) and with three eukaryotic Kir's (Kir7.1, Kir4.1, and Kir2.1). Only those residues that differ from KirBac1.1 are shown for the other KirBac's. Note the relatively large number of residues in the first and last three sequences that are identical to at least one residue in the KirBac sequences. Features unique to Kir's are indicated by numbers under the sequences.
